Xiaomi SU7 Battery Health After 265,000 km Is Stunning

A Chinese owner just revealed the health status of his Xiaomi SU7 after covering 265,000 kilometers in just 18 months. With intensive daily driving of 600 kilometers and over 500 charging cycles, the battery still shows 94.5% capacity. A performance that far exceeds market expectations for electric vehicles.

"I expected at best 90%. Seeing 94.5% was a real surprise." — M. Feng, Xiaomi SU7 owner

600 kilometers a day for 18 months

M. Feng unknowingly conducted a real-world durability experiment on electric battery lifespan. This SU7 Pro owner accumulated 265,000 kilometers in 18 months, averaging 600 kilometers daily. Usage that far exceeds normal patterns and really puts the 94.3 kWh battery through its paces.

The math is telling: with this intensive use, the battery went through the equivalent of 506 complete charge-discharge cycles. In reality, the cycle count is probably higher, since most drivers never let their battery fully drain before recharging.

Health status that defies predictions

A check at a Xiaomi authorized service center revealed a SoH (State of Health) of 94.5%. This measurement corresponds to the remaining maximum capacity of the battery compared to its new condition. According to the CarNewsChina report, the owner "expected at best 90%."

To put this in perspective, most manufacturers today guarantee their batteries for 8 years or 150,000 kilometers, with a minimum threshold of 70% remaining capacity. The SU7 far exceeds these standards with nearly double the guaranteed mileage.

Other components are holding up too

Longevity isn't just about the battery. According to information from Chinese media, the brakes have never been replaced despite the high mileage. The cooling system shows no anomalies either.

These results suggest overall degradation is contained—far from the usual concerns about electric vehicle wear. The LFP (lithium iron phosphate) technology used by Xiaomi appears particularly resistant to repeated cycling.

What battery technology does the SU7 use?

The SU7 is equipped with an LFP (lithium iron phosphate) battery supplied by CATL, one of the world's leading cell manufacturers. This technology, known for being more stable and durable than conventional lithium-ion batteries, generally offers better resistance to repeated charge cycles.

The sedan's 800V architecture enables rapid charging and high power output. This technical design probably contributes to the observed longevity by avoiding excessive thermal stress during charging.

Perfectly timed publicity for Xiaomi

This revelation comes at exactly the right moment for Xiaomi, which is preparing the SU7 refresh expected on March 19th. Prices for the updated version range between 229,900 and 309,900 yuan (roughly €28,000 to €37,000), up from the current model.

The Chinese brand is betting big on reliability to win over European buyers. With models like the upcoming 990-horsepower YU7 GT, Xiaomi wants to replicate the Tesla strategy: create a halo effect with spectacular models to lend credibility to the entire lineup.

When's it coming to Europe?

Xiaomi hasn't yet announced a specific timeline for Europe. The brand is focusing first on its home Chinese market before considering international expansion. The SU7's longevity results nonetheless make a powerful argument for convincing European buyers, who traditionally remain wary of Chinese brands.

This real-world feedback shatters misconceptions about electric battery degradation. With 94.5% capacity after 265,000 kilometers, the SU7 proves that electric vehicles can rival combustion engines in durability—and possibly exceed them.
